Abstract: 21,153. Saxton, A. H., Saxton, F. S., and Bachmayer, J. J. Sept. 18. Tying or knotting.- Relates to a machine for tying-up bundles, particularly bundles of vegetables, and consists chiefly in providing means to enable the machine to tie bundles of various sizes, and means for adjusting and controlling auxiliary tying- mechanism when it is desired to tie bundles in two different places at the same time. The machine comprises a frame 2, Figs. 1 and 3, which supports the treadle driving - gear 32<c>, and the table 28, and has at one end a standard 8 with a tubular arm 9 projecting over the table. The arm 9 forms a bearing for the shaft of the device 10 for knotting the cord. This knoting-mechanism is of well-known type, and comprises a rotating knotting-bill 15, Fig. 10, a movable guard-plate and knife-plate 25<b>, a retaining hook 11<b>, and a cord clamp or " shuttle " 13. The shaft of the knotting-device has mounted an its outer end a sproket-wheel 17, which is continuously driven from the driving shaft 8<1>, and a crank-arm 24 and a connecting-rod 23 which is yieldingly connected through a spring 23<a> with an arm 21 secured to a shaft 20. A cord-tensioning device consisting of a bar 30 having a disk resiliently attached to its lower end is secured to the frame in front of the needle. The cord passes through holes in the disk and the bar. The shaft 20 carries the curved two-prong needle 22 which co-operates with the knotting-mechanism to tie the cord around the bundle. The sprocket 17 and the shaft on which it is mounted each carry one member of a clutch normally held out of engagement by a trip attached to a rod 29. This rod has its other end bent to form an arm 29<1> which projects into the path of the bundle as it is pushed into the machine. When the arm 29<1> is moved, the trip releases the clutch and allows the knotter to make one complete operation. The table 28 is pivoted at one end to arms 6d extending from the frame, and is pressed upwards by springs 27b. The free end of the table engages beneath an horizontal extension 25 which is movable in a vertical direction in guides, but is clamped in the desired position. When the operator moves the bundle that he has assembled on the extension 26 into position beneath the knotter, the table 28, by reason of its spring support 27b, forces the bundle upwards against the knotter and is depressed according to the thickness of the bundle, so that the machine is thus adapted to tie bundles of various sizes. For bundles of small size, an auxiliary spring 28<11>, which is fixed in the slot in the table through which the needle works, presses the bundle upwards against the knotter. The auxiliary tying-mechanism consists of extensions 16<m> and 20<m> of the knotter shaft 16 and of the needle shaft 20, respectively, on which are freely mounted duplicates of the knotter and needle. The knotter disk 18<m> and the needle 22<m> can be moved along the shaft extensions by means of arms 34<1>, 34<11>, Figs. 3 and 4, of a shifter frame, The arm 34<11> has a fork 34<e> which engages the hub of the needle 22<m>, and the arm 34' is secured to a frame 33, which engages the knotter 18<m> for this purpose. The hubs of the needle and of the knotter disk are constructed as clutch members adapted to engage the other clutch members 35 which are feathered on the shaft extensions and are also along them by the shifter frame. The clutches are engaged or disengaged by rods 35<d> connected to a handle 34<b> rotatably mounted on the vertical part of the shifter frame. Thus the operator is enabled, by pulling the handle 34<b>. to move the auxiliary mechanism to any desired position and, by turning the handle, to throw it into or out of gear with the primary mechanism. In order to provide for the movable auxiliary mechanism, the table 28 is provided with an elongated opening in which slides a plate 36<1>, Fig. 6, having a slot for the needle 22<m>. The plate 36<1> is moved by an arm 36<c> extending from the arm 34<11>, and is connected on each side to a series of shutter plates 36b, which also slide in the opening in the table. Thus the opening in the table is filled for every position of the plate 36'.
